Cartesian Coordinate Space

After completion of the molecular dynamics calculation, the partial energy terms for the last molecular dynamics step are stored in the appropriate symbols. The name of the symbols is given by $energy-term (see Section 4.5). The overall energy (Eq. 4.1) is stored in the symbol $ENER; the rms gradient is stored in $GRAD. The value of the second energy function (Eq. 4.26) is returned in the symbol $PERT. In addition, the following symbols are declared: $TEMP, $TOTE, and $TOTK, which are respectively the temperature, total energy, and kinetic energy. If the IPRFRQ frequency is nonzero, the average values of the energy terms and the temperature are stored in symbols whose names are preceeded by “AVE "; e.g., the average bond energy is stored in the symbol $AVE BOND. These averages are computed over the whole molecular dynamics run.
